About Genesy AI

Genesy AI is a Barcelona-based startup on a mission to revolutionize how B2B sales and prospecting teams operate. Our cutting-edge AI-driven lead generation technology empowers sales teams to focus on what truly matters: selling. By automating manual prospecting, we help optimize workflows, ensuring a predictable and scalable sales pipeline—no wasted time, just results.

After successfully raising €5 million in a landmark seed funding round, we are looking to grow our teams and scale in key markets.

We’re growing fast and looking for a Software Engineer to join us at Genesy AI. You’ll play a key role in building the systems and user experiences that power our sales-automation platform, from high-throughput backend workflows to performant, feature-rich web applications.

💪🏻 What You’ll Do

Depending on your background and strengths, you will take ownership across one or more of the following areas:

Backend

  • Build and maintain scalable, reliable services powering our core engine.

  • Work with async architectures, data pipelines, and workflow orchestration (Temporal).

  • Design and implement production-grade APIs and integrations with external platforms (CRMs, LinkedIn, and more).

  • Optimize performance, debug complex issues, and ensure strong observability.

Frontend

  • Develop high-quality, responsive web applications using React + TypeScript.

  • Own customer-facing dashboards, campaign builders, reporting UIs, and supporting API layers.

  • Work on internal tools, SSR/edge rendering, and lightweight Node.js services.

  • Focus on performance, Core Web Vitals, and developer experience.

Cross-functional

  • Collaborate closely with Product, Design, and Engineering teams.

  • Ship end-to-end functionality with a clear focus on quality, reliability, and speed.

  • Help shape engineering practices, code quality, and architecture as we scale.

🔎 What We’re Looking For (Must-Have)

  • 3+ years of professional software engineering experience (Backend, Frontend, or Full-Stack).

  • Strong experience with TypeScript and either Node.js or React.

  • Solid understanding of modern API design, async workflows, or web architectures.

  • Experience working with relational databases (PostgreSQL or similar).

  • Ability to work autonomously, debug complex issues, and ship high-quality code.

  • Strong communication skills and an advanced level of English.

  • Desire to work in a fast-moving startup environment.

➕ Nice-to-Have

  • Experience in early-stage or fast-scaling startups.

  • Familiarity with workflow engines (e.g., Temporal), distributed systems, or microservices.

  • Knowledge of UI performance optimization, design systems, or a11y testing.

  • Experience with Redis, Elasticsearch, Kafka, or third-party API integrations.

  • CI/CD practice with GitHub Actions.

  • Interest in B2B SaaS, sales tech, or automation tools.

  • Basic exposure to full-stack work, even if your focus is mainly Backend or Frontend.
